It's fine, but I beg of the internet movie going community at large to stop being so defensive of Pixar.
This movie is not in the vein of others (Save someone, stop something, time is running out), it's kids just chilling and learning. And while that's fine, I can see how people think it's very light on story. If you want something on vaguely in the background, you can do much worse.
I have never been that person who thinks Pixar can do no wrong - and that's outside of cheap shots at the Cars movies, by the way. People being offended that people rate something that isn't the copy and paste of their plotlines is rated a little lower is ridiculous.
